Inscribed and central angles

This is a fully customization Geometry manipulative that can be useful in the teaching and learning about the properties of angles, inscribed angles, central angles, arc lengths, and arc measures. Use two rubber bands to discover the relationship between inscribed and central angles. it would be ideal to make the rubber bands two different colors in order for students to differentiate between the inscribed and central angles. To save material I suggest making this a group project and make 4-5 printed models.
